better UV filter

wondering if anyone knows where to get UV blocking filter, preferably
plastic and clear. i wish to add another UV filter to my auto-dark helmet.
helmet has what appears to be a spot on the inside that can hold another
filter.
i thought Edmond Optics may have something but they never replied to my
email.
thnaks,

Why? The specs I've seen on welding helmets seem to be pretty good. The "spot" on the inside is to hold a clip in lens. I have a 2.00 diopter one in my hat.

Why do you want to add another UV filter? There is no evidence that the standard welding helmet lets enough UV through for eye problems to appear. Actually, even plain glass is quite opaque to UV...

blocking more UV/IR can only be better.

Same philosophy as, "If two asprins can cure a headache, two dozen must be better."
